DIE CAST RETROFIT PUMP HNGR-RTRNLS 450

The Holley 12-159 In-Tank RetroFit Fuel Module allows for easy conversion to an in-tank EFI fuel system, fitting fuel tanks from 7" to 12" deep. It features a low-profile 5-inch diameter design, extending only 1.275 inches above the tank mounting surface, and an innovative clamping system that allows 360-degree rotation and flexible placement. It includes a Holley Hydramat (3" x 15" with 6 clocking pin locations) for consistent fuel supply and clearance, and is constructed from die-cast aluminum for corrosion resistance. With 1/4" NPT ports, it's ideal for Terminator EFI, Sniper EFI, MSD Atomic EFI, or any TBI/EFI conversion, available with 255 LPH or 450 LPH fuel pump options for return and returnless systems. A 30 amp fuel pump relay and minimum 12 gauge wire are recommended, with -6 AN lines and fittings as the maximum recommended size.
